How to play YouTube video in Android application ?

As we know playing a video stored in user device will never be a solutions specially if you app contains a large amount of information’s like a city guide, e-learning app... and so on and storing it locally we surely abuse the user and push him to uninstalled. So in this tutorial we are going to play a YouTube video with tow different methods and we are going also to play a video from an SDCARD as a demonstration of the Video View component

 Very important playing a video with android emulator will never work properly you must use a real android device for testing This method will launch the YouTube app and not in a videoview All you have to do is to paste this code inside the event of your button and don't forget to replace video_id by the located on the URL of YouTube video you want to play

String video_id = "2vFLW-idOxk";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("vnd.youtube://" + video_id);
startActivity(intent);

you can also use this method for clean and nice coding

private void startVideo(String videoID) {
 // default youtube app
 Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("vnd.youtube:" + videoID));
 List list = getPackageManager().queryIntentActivities(i, PackageManager.MATCH_DEFAULT_ONLY);
 if (list.size() == 0) {
  // default youtube app not present or doesn't conform to the standard we know
  // use our own activity
  i = new Intent(getApplicationContext(), YouTube.class);
  i.putExtra("VIDEO_ID", videoID);
 }
 startActivity(i);
}

Add the following permissions in the manifest file
